On Dec. 19, some 6,000 campesinos and their supporters filled the streets of Chiclayo, capital of Peru's northern Lambayeque region, demanding the repeal of the National Water Authority's resolutions  089-2012 and 090-2012, which authoritize La Zanja mining company to begin dumping waste water in the canyons of La Pampa and El Cedro, inland across the border in Cajamarca region. These canyons empty into the Río Chancay, which flows back into Lambayeque (where it joins with the Río Reque to meet the sea near Chiclayo). The rally concluded at the Lambayeque regional government headquaters, where representatives of different organizations making up the Lambayeque Unitary Struggle Command (CULL) delivered a message to regional president Humberto Acuña Peralta, demanding that he take immediate action to protect the waters of the Río Chancay.

On Oct. 1, the indigenous village of San Juan Bautista de Cañaris in Peru's northern region of Lambayeque announced the results of a consulta, or community consultation, on the proposed Cañariaco Norte open-pit copper mine, saying 1,896 members of the pueblo of some 4,000 voted by 95% to reject it. The results were immediately forwarded to the Energy and Mines Ministry (MINEM). Vancouver-based Candente Copper, which hopes to develop the project, issued a statement rejecting the consulta, saying the community had already approved the project in a "general assembly" held on July 8. The statement noted that the "general assembly" has been called for judicial authorities after Cristobal Barrios, the president of the Cañaris Campesino Community, had refused to convene it. The statement said the "general assembly" had been confirmed as "legally binding" by MINEM, and charged that Barrios had called the consulta "unilaterally" in violation of Peru's General Law of Campesino Communities (PDF). Cañaris community representatives, in turn, noted that more residents participated in the consulta than in the "general assembly," and insisted that the new vote represents the will of the community. (Marketwire Canada, Bloomberg, Oct. 2; El Comercio via Gato Encerrado, Diario Correo, Oct. 1)
